Each row is one source-specific observation. Repeated measurements of this compound are not independent compounds. Direct binding, functional displacement and cellular outcomes retain their distinct endpoints.

No observations match these filters. Missing curation is not evidence of biological inactivity.

Exact deposited instances

Experimental structures

Native-core and broader Pfam proximity are distinguished from contacts elsewhere in a protein. Each action opens the actual deposited ligand instance. Geometric proximity does not supply a measured binding affinity.
